@bubblefat_
I have no idea why you would even post your code, since you do not have anything that can try to update it. Even if it did, we would not need to see the entire class if you are just asking how you would do that.

Create a schedular and create a repeating task. Set the wait value to 10*20L (20L is one second), and in the public void run(), update your scoreboard instance.

Please don't compare boo leans with == there is no need, you can do if(Boolean){} and use ! To check for false
